A point is located in quadrant IV if its coordinates have a positive x-value and a negative y-value. For example, the point (3, -2) lies in quadrant IV because the x-coordinate is positive (3) and the y-coordinate is negative (-2). In this quadrant, points are found to the right of the origin and below the x-axis.
The point (1,3) is located in the first quadrant.
If a point is not in a quadrant, it means that its coordinates do not place it in one of the four quadrants defined in the Cartesian plane. The quadrants are determined by the signs of the x and y coordinates: Quadrant I (positive, positive), Quadrant II (negative, positive), Quadrant III (negative, negative), and Quadrant IV (positive, negative). A point could be located on one of the axes (x-axis or y-axis) or at the origin (0,0), which are not considered part of any quadrant.

The point (2, 3) is located in the 1st quadrant
If A is in quadrant IV, then A/2 is in quadrant II. Yes, the fact than cos(A) is 0.1 means that A is in quadrant I or IV, but it really is not required in order to answer the question. It is superfluous.
The point (1,3) is located in the first quadrant.

The quadrant where a point has a negative x coordinate and a negative y coordinate is located in quadrant 3.

The point (8,0) is on an axis (abscissa axis or x-axis) and is therefore not in a quadrant.
